a "corporation of Delaware Application October 6, 1932, 'Serial No.636,481 Renewed October 16, 1936- 14 Claims.

My invention relates to cartons for packaging, shipping;jstoraging andvending articles of various kinds, such, for example, as chinawaredishes and cups, bottles and the like.

In general, my invention has for an object the provision of a cartonadapted to contain a numberof dishes, plates, bottles or other articlesin a single unit adapted for sale as such to the consumer, and by meansof which the amount of loose packing, such as excelsior or the like,required for the packing of fragile articles of the class described, maybe materially reduced or eliminated.

An object of my invention is 'to provide a carton formed from a singlecontinuous sheet of material, adapted to-contain a plurality of articlesfor shipment, storage or sale as a single unit,and having self-formedpartitions adapted to separate said articles, which partitions dividethe carton into a plurality of recesses each adapted to receive andretain one of said articles and shaped in accordance therewith.

A further object of my invention is to provide a carton for the purposeset forth above which is provided with exterior walls of doublethickness over a sufficient portion-of the carton to provide mechanicalstrength sumcient to prevent damage or injury to the carton and itscontents under conditions of shipment, handling and storage.

A further object of my invention is to provide a blank for forming acarton of the character and for the purpose hereinabove set forth, whichis of relatively simple shape or outline and is adapted to be cut from asingle continuous sheet of material with a minimum of waste.

My invention has for further object such additional advantages andimprovements in construction and detail'as may hereinafter be found toobtain.

In the drawings accompanying: and forming a part of this specification Ihave illustrated various forms in which'my inventionmay be embodied. Inthese drawings,

Fig. l is a plan view of a blank for forming a carton in accordance withmy invention;

Fig. 2 is a perspective view of a carton formed from the blankillustrated in Fig. 1, said carton being shown in a partly closedcondition;

Fig. 3 is a perspective view of the carton shown in Fig. 2, in acompletely closed condition;

Fig. 5 is a perspective view of a carton formed from the blank shown inFig. 4, said carton being shown in. a partly closed condition; and-Fig.6 is a perspective view of the carton, shown in Fig; 5,-inacompletely closed condition.

Similar reference numerals designate the same or similar parts in theseveral views of the drawings. 5

Referring'now to the drawings and more particularly Figs. 1, 2 and 3thereof, it will be seen that I provide. a blank having a central panelI which is adapted'to constitute the base or bottom of the carton'whenformed. The central panel I is of rectangular'shape and is defined byscore lines 2, 3, 4 and 5.

Adjoining the panel I along the score lines 2 and4 I provide side panels6 and 1 respectively.

I The sides of the panel 6 which are at right angles to the score line 2are defined by score lines 8 and-9 which'are substantially in alignmentwith and form extensions of the score lines 3 and 5 respectively.Adjoining the side panel 6 along the score lines. 8 and 9 I provide sideextension panels In and II respectively which are in turn adjoined alongscore lines l2 and I3 to end flaps I4 and 15 respectively." The endflaps l4 and I5 are provided with notches I6 and I! adapted for mutualengagement and interlocking when the blank is bent to form a carton asshown in Figs. 2 and 3.

The sides of the panel I at right angles to the score'line 4 are'definedby score lines and 2| which are substantially in alignment with and formextensions to the score lines 3 and 5 respectively. Adjoining the sidepanel 1 along score'lines 20 and 2| I provide relatively narrow spacingpanels 22 and 23 which are in turn adjoined along score lines 24 and 25by partitioning panels 26 and 21. The panels 26 and Zl'are in turnadjoined along score lines 28 and 29 by spacing, panels 30 and 3|,similar to the panels I 22 and 2 3,'respecti'vely. 40

Adjoining the central panel l along the score lines 3 and 5, I provideexterior side panels 32 and 33, respectively, which are in turn adjoinedalong score lines 34and 35 by cover flaps 36 and 31 having notches 38and 39, respectively, which & are adapted to mutually engage andinterlock when'the blank is bent to form a carton as shown in Fig. 3.

Extending outwardly from the four corners of the central panel l, Iprovide straight cuts 40 and. 4.4. which are in alignment with and formextensions of the'score line 2, and also cuts 42 and 43 whichformextensions of the score line 4. The cut 40 and 42 separate the panel32 from the panels l0 and 26 respectively, while the cuts 4| and 43separate the panel 33 from the panels II and 21 respectively.

In this instance, in which the partitions formed by the panels 26 and 21are intended to traverse the carton in planes parallel to the sides 32and 33 when the latter have been bent at right angles to the centralpanel I, the following relationship should exist between variousdimensions of the several panels:

The dimension a of the panels 32 and 33 should equal the dimension D ofthe panels Gand I and the panels adjoining the latter along the scorelines 8, 9, 20 and 2|. The dimension 0 of panels 26 and 21 as well asthe dimension d of panels In and II should equal the dimension e of thecentral panel I. The dimension 1 of the spacing panels 22, 23, 36 and 3%should be equal to about one-third of the dimension 9 of the centralpanel I.

It should be borne in mind, however, that in planning these dimensionsand in cutting and scoring the blank, allowance must be made for thethickness of the material from which the blank is formed. Thus inpractice, especially when material of considerable thickness isemployed, as will be evident from inspection of Fig. 2, the actualdimension 0 of the panels 23 and 2'5 will be slightly smaller than thedimension d of panels Ill and II due to the fact that the panels 26 and21 are intended to form partition members lying within an enclosureformed in part by the panels Ill and II.

It will further be obvious that, especially when material ofconsiderable thickness is employed, such score lines as have been statedhereinabove are substantially in aligmnent with each other or formextensions one of the other may actually be slightly ofiset at thejunctions thereof in order to allow for proper folding of the panels andproper formation of the enclosure. Thus Fig. 1 shows a slight oii'setbetween the score lines 3 and 20, which offset is provided in order topermit the panels 22, 23 and 30 to be folded within the enclosure formedby the panels 5, III, II, I4 and I5.

In forming the carton from the blank shown in Fig. 1, right angle bendsare first made along the score lines 23, 2I, 2t, 25, 28 and 29 in suchmanner as to bring the spacing panels 22 and 23 against the adjacentsurfaces of the panel I, with the spacing panels 3|] and 3! parallel tothe panels 22 and 23 and extending outwardly therefrom. A right anglebend is then made along the score line d, which brings the partitions 26and 21, as well as the spacing panels 22, 23, 3t and 3|, into theposition in which they are shown in Fig. 2.

A right angle bend is then made along the score line 2, bringing theside panel 6 into engagement with the panels 39 and 3 I, and furtherbends are made along the score lines 8, 9, I2 and I3 to bring the panelsII], H, H! and I5 around the structure formed by the panels "I, 22, 23,26, 21, 30 and 3|. When the panels I4 and I5 have been carried aroundthe panel I they are mutually interlocked by means of the notches I6 andII, the carton being at this point virtually in the condition in whichit is shown in Fig. 2.

It will be noted from extension of Fig. 2 that a partial enclosure hasnow been erected upon the central panel I as a base, which enclosure isdivided into three compartments by means of the partitions 26 and 21 andtheir adjacent spacing panels, and which is open at the top, forinsertion of articles therein. The carton which I have specificallyillustrated in the drawings is of such proportions as to be well suitedfor the purpose of packaging three flat articles, such as plates orsaucers and it may be observed at this point that the dimensions b, eand f indicated on Fig. 1 should correspond to the principal exteriordimensions of each of the articles intended to be packaged in thecarton.

It is of course highly desirable that the dishes or other articles,whether wrapped or not, should t into the compartments formed by thepartitions 26 and 2'! and the panels II) and II with sufilcienttightness to hold them securely.

In order to complete the enclosure, right angle bends are made along thescore lines 3, 5, 34 and 35, bringing the panels 32 and 33 face to facewith the panels II) and I I respectively, and bring ing the coveredflaps 36 and 31 into position across the hitherto open end of theenclosure, as

is illustrated in Fig. 3. By means of the notches 38 and 39 the coveredflaps 36 and 31 are interlocked and the enclosure of the carton isthereby made complete.

The carton thus formed needs, for most purposes at least, no additionalsealing or wrapping. The articles packaged within the same are securelyheld and separated from each other, thus reducing breakage or injury toa minimum. The latter property is also greatly enhanced by the fact thatby far the greater portion of the carton is comprised of Walls of morethan one thickness. Thus panels IE] and 32 cooperate to provide a sidewall of a thickness double that of the blank from which the carton ismade.

In the blank and carton shown in Figs. 1, 2 and 3, the panels 25 and 21are adapted to form partitions running lengthwise of the central or basepanel I, that is to say, parallel to the outer side panels 32 and 33when the carton is completed. This form is especially suitable forpackaging fiat or thin articles, such as plates and saucers.

In Figs. 4, 5 and 6, however, I have illustrated a modified form ofblank and carton formed therefrom, in which partitions are providedwhich run transversely with respect to the central or base panel. Thisform is suitable for packaging articles, such as cups, jars, cans andthe like, which are not fiat or thin.

In this modification of my invention, the blank is provided with acentral panel IEI defined by score lines I02, I83, I64 and IE5. Alongthe score lines I02 and IM the panel II is adjoined by end panels I06and. I01, respectively.

The panel I36 is in part defined by score lines H38 and I99 formingextensions of the score lines I33 and I05, respectively.

Along the score line I08, the panel IE6 is connected to a spacing panelI I0 having a notch H I therein and which is adjoined along a score lineII2 by a partitioning panel H3. The latter is in turn adjoined along ascore line I I4 by a spacing panel H5. Along the opposite score lineI89, the panel I36 adjoins a side extension panel H5 having a notch I I7therein.

Similarly but oppositely, the side panel I32, which is partly defined byscore lines H8 and I I3 forming extensions of the score lines I03 andHi5, respectively, is adjoined along the score line I I8 by a sideextension panel I23 having a notch I2I, and along the score line II9 bya spacing panel I22 having a notch W3 and terminating at a score lineI24, where it is adjoined by a partitioning panel I25. The latter is inturn adjoined along a score line I26 by aspacing :panel I21.

Adjacent to the-panel .IOI along the score lines I03 and I051provideouter side panels 132 and 133, respectively, which terminateatscore lines I34 and Iwhere they :are met by cover flaps I30 and I31having notches I38 and I39, respectively,

The carton is brought into the condition in which it is shown in Figs 5by making right angle bends along the score lines II4, "I112, I08, I00,I02, II8, I26, I24, H9 and I04,.and interlocking the notches I I I andI23 with the notches HI and 1, respectively. A' partial enclosure,

open at the top, is formed, having three compartments separated by. thepartitions formed by the panels II3and I25. The side panels I32 and I33and the cover flaps I36 and H41 are then brought up and over the partialenclosure formed in part by the panels 6, I06, I20 and I01, andby'interlocking the notches I38 and I'30,-the carton is completelyformed and the enclosure completed, as is shown in Fig. 6.

Roughly, the dimension 1 of the panels I32 and I33 should equal thedimension m of the panels I06 and I01; the dimension n of the panels H3and I25 should equal the dimension o of the panel IOI; the dimension pof the panels I I0, I I5, I22 and I27 should be equal to one-third thedimension q of the panel IOI and the dimension 1, n and 10 shouldcorrespond to the principal outer dimensions of each of the threearticles or units intended to be packaged in the carton;

It will be obvious to those skilled in the art that my invention iscapable of considerable 'modification in detail within the skill of theart,
